** @name cputest.s Tests 68000 cpu** Based on https://github.com/MicroCoreLabs/Projects/blob/master/MCL68/MC68000_Test_Code/MC68000_test_all_opcodes.X68** Converted into a CD-i system ROM image by CD-i Fan:* - comment lines must start in first column* - replaced org instructions by suitable rept* - copy vectors to low memory at startup* - replaced jsr/jmp by bsr/bra for position independence* - replaced move.l by moveq whenever possible* - converted branches to short form whenever possible (e.g. beq => beq.s)* - added immediate suffix to opcodes where required (e.g. and => andi)* The last three modifications are required to make the test work;* apparently the original assembler was somewhat smarter then* the Microware OS-9 assembler and did this automatically.** In some cases the opcodes of the test are used as test data!** Original file header follows.** File Name : MCL68 Opcode Tests* Used on :* Author : Ted Fried, MicroCore Labs* Creation : 7/14/2020** Description:* ============** Program to test all of the Motorola 68000's opcodes.** If failures are detected, the code will immediately loop on itself.* All addressing modes, data sizes, and opcode combinations are tested.** This code was developed using the Easy68K simulator where all tests passed!**------------------------------------------------------------------------** Modification History:* =====================** Revision 1 7/14/2020* Initial revision***------------------------------------------------------------------------** Copyright (c) 2020 Ted Fried** Permission is hereby granted, free of charge, to any person obtaining a copy* of this software and associated documentation files (the "Software"), to deal* in the Software without restriction, including without limitation the rights* to use, copy, modify, merge, publish, distribute, sublicense, and/or sell* copies of the Software, and to permit persons to whom the Software is* furnished to do so, subject to the following conditions:** The above copyright notice and this permission notice shall be included in all* copies or substantial portions of the Software.** THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR* IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY,* FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
